Of Coke Breeze Sintering Iron Ore

Combustion behavior of granulated coke breeze in iron ore

Dec 01, 2018· 1. Introduction. Iron ore sintering is a very important process which produces sinter as a major burden for blast furnace ironmaking. In this process, iron ore and auxiliary materials, e.g., fluxes, unqualified sinter (called return fine), and coke breeze, are mixed, granulated and then sintered at
